Both statin and fibrate therapies taken to improve lipid profiles decreased the risk of stroke by 30% in a community-dwelling population of elderly people, according to prospective European study published online May 19 in the British Medical Journal.

Participants in almost all the randomized clinical trials assessing cardiovascular drugs are younger than age 70, so the benefits of these agents in older patients – particularly their effectiveness as primary prevention in people who have no known cardiovascular illness – is uncertain. Nevertheless, “in real life, statins are commonly prescribed to older people without clinical evidence of atherosclerosis,” said Dr. Annick Alperovitch of the University of Bordeaux (France) and her associates.

To assess the effects of statin and fibrate therapies on incident cardiovascular events in an elderly population, the investigators analyzed data from an ongoing cohort study of vascular disease among elderly residents of Bordeaux, Dijon, and Montpellier. Dr. Alperovitch and her associates examined the medical records of a subset of 7,484 men and women (mean age 74 years) who were followed every 2 years for a mean of 9 years. A total of 27% reported using lipid-lowering medications at baseline; roughly half used statins and half used fibrates. There were 292 strokes during follow-up.

The risk of stroke was cut by roughly 30% among statin and fibrate users, compared with nonusers (hazard ratio, 0.66). This decrease was similar between the two medications. All-cause mortality was slightly lower in people who took statins or fibrates, compared with nonusers (HR 0.87), the investigators said (Br. Med. J. 2015 May 19 [doi:10.1136/bmj.h2335]).

This is the first observational study to show a significant association between lipid-lowering drugs and decreased stroke risk, they noted.

The overall incidence of stroke in this study was low (0.47 per 100 person-years), so even a 30% decrease produced “a limited number of avoided cases.” That may be attributable in part to the generally healthy lifestyle, high educational achievement, and high economic status of this urban French study population. But if the findings are confirmed in future studies, they could have an important impact on public health in other populations, Dr. Alperovitch and her associates said.

TORONTO – Anxiety is too often being ignored during the transition period between childhood and adulthood, but a new program at Columbia University is trying to change that pattern, The program offers comprehensive treatment of anxiety in affected adults, and perhaps as importantly, their families.

“Anxiety starts by about the age of 4, picks up steam all the way through adolescence, and is our most common condition psychiatric condition amongst children and adolescents,” said Anne Marie Albano, Ph.D. “And it predicts every adult psychiatric diagnosis.”

Dr. Albano is the founder and director of the Columbia University Clinic for Anxiety and Related Disorders (CUCARD), in the division of child and adolescent psychiatry at Columbia University, New York. She discussed anxiety disorder in early adulthood during a session at the annual meeting of the American Psychiatric Association devoted to the latest research in major psychiatric disorders.

“What happens is that at the end of adolescence, we say, ‘Good luck, goodbye, go to school, have a good time, enjoy the rest of your life,’ when in fact, there is a lot more that needs to be done,” she said.

Mood disorders often get treated in college, but anxiety disorders, which very frequently are comorbid with substance abuse, often are not treated.

“When kids get anxious, and then they develop a mood disorder, and they start drinking, that’s when you see suicide attempts and such,” Dr. Albano. “We have neglected the emerging adults. Eighteen to 28 [years] is a dynamic period of development. A lot is going on, and we know it is the period of emergence of serious mental illness.”

Delayed development

Anxiety disorders are highly prevalent in childhood and adolescence, affecting between 10% and 20% of youth. They are significantly impairing, and highly comorbid with mood and substance abuse disorders.

There is evidence that nearly half of children and adolescents treated for anxiety, be it with cognitive-behavioral therapy (CBT), drugs, or a combination of both, ultimately relapse. And part of the reason for this, said Dr. Albano, is that the focus of treatment is generally on symptomatic improvement, which is appropriate. But what is lacking is a focus on functional outcomes, especially developmental trajectories, she said.

“We’re diagnosing these kids at age 4, 5, and 6, so they are taken off track very quickly, compared to their same-age peers in meeting developmental milestones,” Dr. Albano reported. “So by the time you get a 12- or 14-year-old with an anxiety disorder, it’s not just that you’re treating the obsessive-compulsive behavior, or the generalized worry, or social phobia, you have to think about the fact that they are not the same as the kids they have to go back into class with and socialize with; they are not on the same path.”

Parents need help, too

Not only do standard treatments not address development, but they also tend to neglect the role of family involvement.

“We know very well from lots of data that family involvement in anxiety is high, whether it’s chicken or egg,” said Dr. Albano. “Parents get drawn into the cycle of anxiety – they overprotect and overcontrol,” which again puts the child behind in development, because while parental behavior may minimize anxiety in the short term, it solidifies it in the long term.

Not only are parents often overinvolved with their anxious children, but the advice they give often serves to further delay their child’s development. Parents too often help their children avoid uncomfortable situations rather than learn to problem solve and handle them, thereby maintaining the anxiety rather than helping it, said Dr. Albano.

“They are focusing in on ambiguous clues and interpreting them in a negative, anxious way for their children,” she said.

LEAP into adulthood

“At the age of 18 if you’re sending your kid off to college, they better know how to soothe themselves, problem solve, know who they are affirmatively, complete tasks on their own, manage money, to some degree, make and keep relationships, and, especially, take care of their personal selves – get enough sleep, eat right, exercise, and so forth,” said Dr. Albano.

To this end, CUCARD has developed LEAP: The Launching Emerging Adults Program, a treatment program that expands on traditional cognitive-behavioral exposure therapy by integrating the skills needed to help the young people thrive in adulthood. LEAP and Dr. Albano were recently featured in a Wall Street Journal article on good mental health in college students.

The new program, which is run with New York Presbyterian Hospital’s Youth Anxiety Center (YAC), focuses on the unique needs of young adults with anxiety and related disorders and is designed for families struggling with the transition from high school to college, work and career problems, family conflict, limitations in friendships and romantic relationships, and limited independence.

The program also takes on directly the issue of parental overprotection and control, while also addressing inappropriate dependence on parents. Dr. Albano’s team has developed a way of bringing parents into treatment collaboratively with the young adults and without threatening the therapeutic alliance.

Dr. Albano reported receiving honoraria from the American Psychological Association and royalties from Oxford University Press.

SAN DIEGO – Many patients with traumatic brain injury (TBI) can be safely managed by trauma surgeons or intensive care physicians, if a guideline-based individual protocol is followed. In a recent single-center study using this protocol, charges fell, repeat imaging decreased, and patient outcomes did not suffer when neurosurgery consults were reserved for individuals with more severe brain injuries.

Every year, emergency departments see 2.5 million visits for traumatic brain injuries ranging from concussions to devastating open injuries, and 11% of those seen are hospitalized. Still, only 10% of patients with TBI will require neurosurgical intervention, Dr. Bellal Joseph of the University of Arizona said at the annual meeting of the American Surgical Association.

Finding a way to conserve resources is important, said Dr. Joseph, since the total number of emergency department visits for TBI is increasing, but resources remain constrained: neurosurgeons are in shorter supply than ever. Further, TBI management may not be changed by numerous repeat head CTs, which are costly and can expose patients to significant amounts of radiation.

Dr. Joseph and his coinvestigators at the University of Arizona had previously developed Brain Injury Guidelines (BIG), which would mandate repeat head CTs and neurosurgery consults only for larger intracranial bleeds and displaced skull fractures. The guidelines are used as part of an individualized protocol that includes overall clinical assessment and patient-specific factors, such as anticoagulation status and whether the patient was intoxicated at the time of injury.

After a period of education regarding the guidelines, the University of Arizona’s Level I trauma center – the only one in the state – implemented BIG use in 2012. For the 5-year period from 2009 to 2014 encompassing implementation of the guidelines, investigators followed all patients admitted for TBI and tracked use of hospital resources and patient outcomes during the study period.

A total of 2,184 patients with TBI were included in the study, divided into five cohorts by year of admission, and stratified by severity of brain injury. Patients were included if they were admitted for TBI from the emergency department and the initial head CT found a skull fracture or intracranial hemorrhage. Dr. Bellal and his colleagues collected data regarding the number of neurosurgery consults, repeat head CTs, and patient demographic and injury characteristics. They tracked patient outcomes including in-hospital mortality, any progression on repeat head CT, and patient disposition on discharge.

TBI injuries were classified by Glasgow Coma Scale scoring (13-15 for mild TBI; 9-12 for moderate; and less than 8 for severe).

Over time, the proportion of patients with severe brain injury who received repeat head CTs did not change significantly. However, scans for those with less severe injury declined significantly, with a marked drop in repeat head CTs seen at the time of implementation of the BIG guidelines (P < .001 for mild and P = .012 for moderate brain injuries).

Similarly, 100% of patients with severe TBI received a neurosurgical consult in each year of the study period, but the number of consults declined significantly for those with mild and moderate injuries (P < .001 for both mild and moderate injuries).

Hospital length of stay decreased from a mean 6.2 days to 4.7 at the end of the study period (P = .028), and total hospital costs fell by nearly half, from a total $8.1 million for the 2009-2010 cohort to $4.3 million for the 2013-2014 cohort (P < .001).

Mortality, discharge score on the Glasgow Coma scale, and the proportion of patients discharged to home after their hospital stay did not change significantly over the study period.

Study limitations included potential lack of generalizability to smaller or more rural centers, and the potential for confounding by changes in other institutional factors over the study period. The study did not track long-term neurologic or quality of life outcomes.

Discussant Dr. Karen Brasel of Oregon Health & Science University, Portland, said that the study is the latest in a series of reports in the TBI field that speak to the need to avoid “knee-jerk use of resources based on diagnosis alone.” She cautioned that it is still important to examine individual patient outcomes for the few patients who did not receive a neurosurgery consult but then deteriorated, to better evaluate who is at most risk for poor outcomes.

Still, said Dr. Joseph, a “guideline-based individualized protocol for traumatic brain injury can help reduce the burden on neurological services. Life changes, and so does medicine.”

The authors reported no conflicts of interest.

The complete manuscript of this study and its presentation at the American Surgical Association’s 135th Annual Meeting, April 2015, in San Diego, California, are anticipated to be published in the Annals of Surgery pending editorial review.

Researchers believe they have discovered how a commonly administered vaccine protects children from developing acute lymphoblastic leukemia (ALL).

The Haemophilus influenzae Type b (Hib) vaccine is part of the standard vaccination schedule recommended for children by the US Centers for Disease Control and Prevention. The vaccine is routinely given in 4 doses before children reach 15 months of age.

The Hib vaccine prevents ear infections and meningitis caused by the Hib bacterium, but it may also protect against ALL.

This protection has been suggested in previous studies, but it is not well-known among the public at large, and the mechanism underlying this effect has been poorly understood.

Now, researchers have shown that recurrent Hib infections can shift certain genes into overdrive, converting pre-leukemic cells into full-blown cancer. The team described this work in Nature Immunology.

“These experiments help explain why the incidence of leukemia has been dramatically reduced since the advent of regular vaccinations during infancy,” said study author Markus Müschen, MD, PhD, of the University of California San Francisco.

“Hib and other childhood infections can cause recurrent and vehement immune responses, which we have found could lead to leukemia, but infants that have received vaccines are largely protected and acquire long-term immunity through very mild immune reactions.”

For this study, Dr Müschen and his colleagues tested the idea that chronic inflammation caused by recurrent infections might cause additional genetic lesions in blood cells already carrying an oncogene, promoting their transformation to overt disease.

The team conducted experiments in mice and discovered that the enzymes AID and RAG1-RAG2 drive this process. AID and RAG1-RAG2 introduce mutations in DNA that allow immune cells to adapt to infectious challenges, and these enzymes are necessary for a normal and efficient immune response.

The researchers found that, in the presence of chronic infection, AID and RAG1-RAG2 were hyperactivated, randomly cutting and mutating genes.

Additional experiments revealed that AID and RAG1-RAG2 working together is critical to introduce the additional lesions that result in ALL.

Though the researchers focused on a bacterial infection in this study, they believe the same mechanisms may be at work in viral infections.

The team is currently conducting experiments to determine if protection against leukemia is provided by vaccines against viral infections, such as the measles-mumps-rubella vaccine.

The US Food and Drug Administration (FDA) has granted fast track designation to luspatercept for the treatment of patients with transfusion-dependent (TD) or non-transfusion-dependent (NTD) β-thalassemia.

Luspatercept is a modified activin receptor type IIB fusion protein that acts as a ligand trap for members of the transforming growth factor-β (TGF-β) superfamily involved in the late stages of erythropoiesis.

The drug regulates late-stage erythrocyte precursor differentiation and maturation. This mechanism of action is distinct from that of erythropoietin, which stimulates the proliferation of early stage erythrocyte precursor cells.

Luspatercept is currently in phase 2 trials in patients with β-thalassemia and individuals with myelodysplastic syndromes (MDS). Data from the trial in β-thalassemia were presented at the 2014 ASH Annual Meeting, and results from the MDS trial were recently presented at the 13th International Symposium on Myelodysplastic Syndromes.

Acceleron Pharma Inc. and Celgene Corporation are jointly developing luspatercept.

About fast track designation

The FDA’s fast track program is designed to facilitate the development of new drugs that are intended to treat serious or life-threatening conditions and that demonstrate the potential to address unmet medical needs.

The designation provides pharmaceutical companies with the opportunity for more frequent interaction with the FDA while developing a drug. It also allows a sponsor to submit sections of a biologics license application on a rolling basis, as they are finalized.

“The FDA’s fast track designation for the luspatercept development program recognizes the serious unmet medical needs of patients with β-thalassemia and the potential for luspatercept in this area,” said Jacqualyn A. Fouse, president of hematology/oncology for Celgene.

“Celgene and Acceleron are working diligently to initiate a phase 3 clinical program in 2015 to treat patients with β-thalassemia, and we look forward to continuing to work closely with health authorities and other important stakeholders to advance this program.”

Phase 2 trial in β-thalassemia

At ASH 2014, researchers presented results of a phase 2 trial in which they investigated whether luspatercept could increase hemoglobin levels and decrease transfusion dependence.

The goal was to increase hemoglobin levels 1.5 g/dL or more for at least 2 weeks in NTD patients and decrease the transfusion burden by 20% or more over 12 weeks in TD patients.

Thirty patients, 7 TD and 23 NTD, received an injection of luspatercept every 3 weeks for 3 months at doses ranging from 0.2 mg/kg to 1.0 mg/kg.

Three-quarters of patients who received 0.8 mg/kg to 1.0 mg/kg of luspatercept experienced an increase in their hemoglobin levels or a reduction in their transfusion burden.

Of the NTD patients, 8 of 12 with iron overload at baseline experienced a reduction in liver iron concentration of 1 mg or more at 16 weeks.

TD patients had a more than 60% reduction in transfusion burden over 12 weeks. This included 2 patients with β0 β0 genotype, who experienced a 79% and 75% reduction.

Luspatercept did not cause any treatment-related serious or severe adverse events. The most common adverse events were bone pain (20%), headache (17%), myalgia (13%), and asthenia (10%).

There was 1 grade 3 dose-limiting toxicity of worsening lumbar spine bone pain. And 3 patients discontinued treatment early, 1 each with occipital headache, ankle pain, and back pain.

Enoxaparin for injection

Cancer patients with brain metastases who develop venous thromboembolism can safely receive the anticoagulant enoxaparin without further

increasing their risk of intracranial hemorrhage, according to a study published in Blood.

Cancer patients with brain metastases are known to have an increased risk of intracranial hemorrhage, but it has not been clear whether receiving anticoagulant therapy further increases that risk.

So a group of researchers set out to assess the risk of intracranial hemorrhage in cancer patients with brain metastases who received the low-molecular-weight-heparin (LMWH) enoxaparin.

Jeffrey Zwicker, MD, of Harvard Medical School in Boston, Massachusetts, and his colleagues studied the medical records of 293 cancer patients with brain metastasis, 104 of whom had received the LMWH enoxaparin and 189 who did not.

The researchers matched the patients in each group by the year of brain metastases diagnosis, tumor type, age, and gender. The team conducted a blinded review of radiographic imaging and categorized intracranial hemorrhages as “trace,” “measurable,” and “significant.”

At 1 year of follow-up, there was no significant difference between the treatment groups regarding the incidence of intracranial hemorrhage.

Nineteen percent of patients in the enoxaparin arm had measurable intracranial hemorrhages, compared to 21% of patients in the control arm (P=0.97). And 21% of patients in the enoxaparin arm had significant intracranial hemorrhages, compared to 22% of patients in the control arm (P=0.87).

The cumulative incidence of intracranial hemorrhage was 44% in the enoxaparin arm and 37% in the control arm (P=0.13).

In addition, there was no significant difference in overall survival between the treatment arms. The median overall survival was 8.4 months in the enoxaparin arm and 9.7 months in the control arm (P=0.65).

“While it is a very common clinical scenario to treat a patient with a metastatic brain tumor who also develops a blood clot, before this study, there was very little data to inform the difficult decision of whether or not to anticoagulate these patients,” Dr Zwicker said.

“Our findings, which demonstrate that current practice is safe, should reassure physicians that anticoagulants can be safely administered to patients with brain metastases and a history of blood clots.”

Micrograph showing AML

The US Food and Drug Administration (FDA) has granted fast track designation to AG-120 for the treatment of patients with acute myelogenous leukemia (AML) who harbor an isocitrate dehydrogenase-1 (IDH1) mutation.

AG-120 is an oral, selective inhibitor of the mutated IDH1 protein that is under investigation in two phase 1 clinical trials, one in hematologic malignancies and one in advanced solid tumors.

Data from the phase 1 trial in hematologic malignancies were previously presented at the 26th EORTC-NCI-AACR Symposium on Molecular Targets and Cancer Therapeutics in November 2014.

Updated data from this trial are scheduled to be presented at the 20th Annual Congress of the European Hematology Association (EHA) next month.

About fast track designation

The FDA’s fast track drug development program is designed to expedite clinical development and submission of new drug applications for medicines with the potential to treat serious or life-threatening conditions and address unmet medical needs.

Fast track designation facilitates frequent interactions with the FDA review team, including meetings to discuss all aspects of development to support a drug’s approval, and also provides the opportunity to submit sections of a new drug application on a rolling basis as data become available.

“We are pleased that now both AG-120 and AG-221 have been granted fast track designation, demonstrating the FDA’s commitment to facilitate the development and expedite the review of our lead IDH programs as important new therapies for people with AML who carry these mutations,” said Chris Bowden, MD, chief medical officer of Agios Pharmaceuticals, Inc., the company developing AG-120 in cooperation with Celgene Corporation.

Phase 1 results

At the EORTC-NCI-AACR symposium, researchers presented results from the ongoing phase 1 trial of AG-120 in hematologic malignancies. The data included 17 patients with relapsed and/or refractory AML who had received a median of 2 prior treatments.

The patients were scheduled to receive AG-120 in 1 of 4 dose groups: 100 mg twice a day, 300 mg once a day, 500 mg once a day, and 800 mg once a day over continuous, 28-day cycles.

Of the 14 patients evaluable for response, 7 responded. Four patients achieved a complete response, 2 had a complete response in the marrow, and 1 had a partial response.

Responses occurred at all the dose levels tested. The maximum-tolerated dose was not reached. All responding patients were still on AG-120 at the time of presentation, and 1 patient with stable disease remained on the drug.

Researchers said AG-120 was generally well-tolerated. The majority of adverse events were grade 1 and 2. The most common of these were nausea, fatigue, and dyspnea.

Eight patients experienced serious adverse events, but these were primarily related to disease progression.

One patient experienced a dose-limiting toxicity of asymptomatic grade 3 QT prolongation at the highest dose tested, which improved to grade 1 with dose reduction. The patient was in complete remission and remained on AG-120 at the time of presentation.

There were 6 patient deaths, all unrelated to AG-120. Five deaths occurred after patients discontinued treatment due to progressive disease, and 1 patient died due to disease-related intracranial hemorrhage while on treatment.

“We look forward to presenting new data from the ongoing phase 1 study at the EHA Annual Congress next month,” Dr Bowden said, “and remain on track to initiate a global, registration-enabling, phase 3 study in collaboration with Celgene in AML patients who harbor an IDH1 mutation in the first half of 2016.”

“We look forward to presenting new data from the ongoing phase 1 study at the EHA Annual Congress next month,” Dr Bowden said, “and remain on track to initiate a global, registration-enabling, phase 3 study in collaboration with Celgene in AML patients who harbor an IDH1 mutation in the first half of 2016.”

Menopausal hormone therapy is associated with an increased risk of major gastrointestinal bleeding, particularly in the lower gastrointestinal tract, that is associated with duration of use, a study has found.

Analysis of data from 73,863 women enrolled in the Nurses’ Health Study II in 1989 showed that current users of menopausal hormone therapy had a 46% increase in the risk of a major gastrointestinal bleed and a more than twofold increase in the risk of a lower GI bleed or ischemic colitis, compared with never users, said Dr. Prashant Singh of Massachusetts General Hospital, Boston.

Past users showed a much smaller increase risk of bleeding, while increasing duration of hormone therapy was significantly associated with increasing risk of major and low gastrointestinal bleeding.

“Although our findings show that menopausal hormone therapy may increase the risk of major GI bleeding, especially in the lower GI tract, it is important for these patients to know that this therapy is still an effective treatment; however, both clinician and patient should be more cautious in using this therapy in some cases, such as with patients who have a history of ischemic colitis,” Dr. Singh said at the annual Digestive Disease Week.

Dr. Singh does not have any relevant financial or other relationship with any manufacturer or provider of commercial products or services that he discussed during the presentation.

WASHINGTON – A simple urine test could detect gastric cancer even at an early stage, the test’s developers say.

The test, which looks for the presence of two metalloprotease enzymes labeled ADAM 12 and MMP-9/NGAL had 77.1% sensitivity and 82.9% specificity for gastric cancer when tested in 35 patients with the malignancy and an equal number of healthy controls, reported Dr. Takaya Shimura from the department of surgery at Boston Children’s Hospital and Harvard Medical School in Boston.

“This study represents the first demonstration of the presence of ADAM 12 and MMO-9/NGAL complex in the urine of gastric cancer patients,” he said at the annual Digestive Disease Week.

Dr. Stephen J. Meltzer of Johns Hopkins University, Baltimore, commented in an interview that the findings are convincing but preliminary.

A randomized clinical trial enrolling a larger number of patients and controls would be required before he would consider screening patients for the enzymes, said Dr. Meltzer, who was not involved in the study and comoderated the meeting session where the results were presented.

ADAM 12 (a disintegrin and metalloprotease 12) and MMP-9 (matrix metalloprotease 9) are both members of a family of enzymes involved in cellular adhesion, invasion, growth, and angiogenesis, Dr. Shimura explained. MMP-9, when complexed with NGAL (neutrophil gelatinase associated lipocalin) is protected from autodegradation.

The investigators, from the lab of Dr. Marsha A. Moses at Boston Children’s Hospital, and their collaborators in Japan had previously reported that MMPs in urine were independent predictors of both organ-confined and metastatic cancer.

Urinary assays are noninvasive, using easily accessed tissues that can be handled simply and inexpensively, making them ideal for cancer detection, Dr, Shimura said.

Current tests for gastric cancer, such as carcinoembryonic antigen (CEA) and cancer antigens (CA) 19-9 and 72-4, have poor sensitivity for detecting advanced disease, and are even worse at spotting early disease, he noted.

To see whether they could improve on the current lot of tests, the investigators enrolled 106 patients in a case-control study, settling eventually, after age and sex matching, on a cohort of 70 patients: 35 with primarily early-stage gastric cancer, and 35 healthy controls.

After screening the urine of participants for about 50 different antigenic proteins, they found that the patients with gastric cancer had significantly higher levels in their urine of both ADAM 12 (P < .001) and the MMP-9/NGAL complex (P = .020).

In a multivariate analysis, they showed that both enzymes were strong, independent predictors of gastric cancer, with an odds ratio for urinary MMO-9/NGAL of 6.71 (P = .002), and an OR of 15.4 for ADAM 12 (P = .002). In contrast, Helicobacter pylori infection was associated with a nonsignificant OR of 2.54.

In a receiver operating characteristic (ROC) analysis, they also found that MMP-9/NGAL was associated with an area-under-the curve (AUC) of 0.657 (P = .024), ADAM 12 was associated with an AUC of 0.757 (P < .001), and that the two combined had an AUC of 0.825 (P < .001).

As noted before, the sensitivity of the combined enzymes was 77%, and the specificity was 83%.

Finally, using immunohistochemical analysis, the investigators were able to show that gastric cancer tissues had high levels of coexpression of MMP-9 and NGAL (P <.001) and high expression levels of ADAM 12 (P < .001), compared with adjacent normal tissues.

WASHINGTON – A novel, edible colon preparation could make obsolete the fasting and large volume of salty liquid cleansing that keep many a patient from completing their colonoscopies.

A pilot study showed that all 10 patients who ate a series of nutritionally balanced meals, drinks, and snacks such as pretzels and pudding had a successful colon cleansing according to the endoscopist at the time of the procedure, Dr. L. Campbell Levy of Dartmouth-Hitchcock Medical Center in Lebanon, N.H., reported at the annual Digestive Disease Week.

The preparation, which is blended with polyethylene glycol 3350, sorbitol, and ascorbic acid, did not produce any significant changes in electrolytes or creatinine.

There were no adverse events and, equally important, all 10 patients said that they would follow the edible bowel regimen again for a subsequent procedure.

In a video interview, he discussed the small study’s results and the plans for larger, randomized studies.

Dr. Levy reported no relevant conflicts. The inventor of the diet and the founder of Colonary Concepts were involved in the study.
